You have put your operational code in as part of the Class SimpleOperator.

This means that when the register creates the Class your code is run, which is the wrong time and has no context.

Take the bpy.ops.transform.translate code and move it out of the Class definition and move it into the main function e.g.

def main(context):
    for ob in context.scene.objects:
        print(ob)
    bpy.ops.transform.translate(value=(0, 2.20362, 0), orient_type='GLOBAL', orient_matrix=((1, 0, 0), (0, 1, 0), (0, 0, 1)), orient_matrix_type='GLOBAL', constraint_axis=(False, True, False), mirror=True, proportional='DISABLED', proportional_edit_falloff='SMOOTH', proportional_size=1, release_confirm=True)


Now when you run the test call

bpy.ops.object.simple_operator()


It will print out all the Object names and then try and Translate the currently selected Object
